IDEA多线程下多个线程切换断点运行调试的技巧

多线程调试设置可以参考：http://www.cnblogs.com/leodaxin/p/7710630.html

1 断点设置如图：

2 测试代码，然后进行debug

package com.daxin;

import java.util.HashMap;
/**

Created by Daxin on 2017/10/22. */ public class HashMapInfiniteLoop { private static HashMap<Integer, Integer> map = new HashMap<Integer, Integer>(2, 0.75f);
public static void main(String[] args) throws InterruptedException { map.put(5, 55);

         map.put(</span>7, 77);<span style="color: #008000;">//</span><span style="color: #008000;">断点位置 1</span>



 System.out.println(map); }
    }.start();

            map.put(</span>3, 33);<span style="color: #008000;">//</span><span style="color: #008000;"> 断点位置2</span>

 System.out.println(map); }
    }.start();


    </span><span style="color: #008000;">//</span><span style="color: #008000;"> 断点位置 3</span>
    System.out.println("Thread-Main-Name Start"<span style="color: #000000;">);
    System.out.println(</span>"Thread-Main-Name Start"<span style="color: #000000;">);

    Thread.sleep(</span>500000<span style="color: #000000;">);
